2. It is a maxim that every man's house is his castle, and it is protected from every unlawful invasion. An officer having a lawful process, of a criminal nature, authorizing him to do so, may break an outer door, if upon making a demand of admittance it is refused. The house may also be broken open for the purpose of executing a writ of habere facias possessionem. 5 Co. 93; Bac. Ab. Sheriff, N 3.
3. The house protects the owner from the service of all civil process in the first instance, but not, if once lawfully arrested, he takes refuge in his own house; in that case the officer may pursue him, and break open any door for the Purpose. Foster, 320; 1 Rolle's R. 138 Cro. Jac. 555. Vide Door; House.
